emulate mouse move in default implementation of QPlatformCursor::setPos

Browse Source 
When QCursor::setPos() is called and the platform plugin doesn't
implement QPlatformCursor::setPos, a warning is printed.
Additionally, we now emulate a mouse move to have a default
implementation that's actually useful.

QPlatformCursor::pos() now returns the position that was set by
QPlatformCursor::setPos(), or other facilities that generate mouse events,
for example the Tslib plugin.
